Description
The Vermason Portable Ionising Air Gun
is a ready-to-use unit for use in
applications and areas where
electrostatic charge can create
manufacturing or handling problems.
This unit quickly and effectively
neutralises bulk static charges and aids
in controlling contamination by
dislodging dust and debris attracted by
static electricity.
The Portable Ionising Air Gun meets or
exceeds the recommended technical
requirements of of EN 61340-5-1 Test
method A.6 for ionization tested per
Figure A.23 for compressed gas guns or
nozzles.
“Ionizers should be considered as a
method for charge neutralization in
cases where grounding cannot be
achieved. These may include localized
(bench) ionized air blowers, compressed
air ionizers, spot ionizers, tape
dispenser ionizers and total room
ionizers.”
“Air ionization can neutralize the static
charge on insulated and isolated objects
by producing separate charges in the
molecules of the gases of the
surrounding air. When a static charge is
present on objects in the work
environment, it will be neutralized by
attracting opposite polarity charges from
the ionized air. Note that ionization
systems should not be used as a
primary means of charge control on
conductors or people.
As with all ionizers, periodic
maintenance will be needed to provide
optimum performance.” (EN 61340-5-2
paragraph 5.2.9)
The Portable Ionising Air Gun is
designed for point-of-use applications.
Ionisers are useful in preventing
electrostatic charge generation,
ElectroStatic Discharge, and
ElectroStatic Attraction. Ionisation is
used to neutralise charges on process
necessary insulators and isolated
semiconductors. Some examples of
process necessary insulators are: the
PC board itself, plastic test stands,
plastic housing where a PCB may be
mounted, as well as computer monitor
screens and regular cleaning wipes.
Examples of floating or isolated
conductors are: loaded PCB mounted in
a stand where the pins are not
contacting the dissipative workstation.
NOTE: The unit is not recommended for
continuous use.
THEORY OF OPERATION
The emitter is located inside of the
nozzle. This emitter produces large
amounts of positive and negative ions,
which mix with the air supply and create
a highly effective neutralising field. Any
material within this field will be
neutralised rapidly. The ionising air flow
removes contamination by dislodging
dust and debris which is attracted to a
material's surface by static charges.
Once static charges are neutralised,
dust particles and other forms of
contamination are freed and carried
away by the air stream. Vermason
ionisers meet the ANSI/ESD S20.20
minimum recommended technical
requirement range of less than ±50 V
voltage offset tested in accordance with
ANSI EOS/ESD S3.1. The Vermason
Portable Ionising Air Gun provides ±30
volt balance.
CAUTION
The Portable Ionising Air Gun is not
water resistant, therefore, keep it away
from water and mist as they will cause
short circuit and insulation failures
Keep the air gun away from vibration,
corrosive/flammable gas and dust as
they can be the cause of fire, short
circuits, rust, etc.
Do not operate the Portable Ionising Air
Gun near the face.
Keep the Portable Ionising Air Gun away
from children.
DO NOT use the Portable Ionising Air
Gun for purposes other than its designed
purpose.
DO NOT damage the nozzle or
connectors.
DO NOT disassemble the unit.
Packaging
1 Portable Ionising Air Gun
1 Coiled Air Tube
1 Quick Disconnect Adapter
1 Extension Brush
4 AA Alkaline Batteries
1 Certificate of Calibration
Installation
I. Open the Battery Container Lid by
using a coin to turn the plastic lock.
II. Insert 4 AA Batteries then close and
lock the lid.
III. Insert the 4 mm diameter air tube to
the Air Inlet and check to see if the
connection is secure.
IV. Connect one end of the Quick
Disconnect Adapter to the air
supply/source and the other end to
the air tube from the Ionising Air
Gun.
NOTE: Ensure that the air supply/
source is set within the 10 - 65 PSI
range.

Features and Components
Operation
AIR INJECTION TEST
Pulling the trigger lightly, approximately
halfway, will release air from the emitter
nozzle. The Active Power LED located
on the backside of the unit should not
illuminate.
If the air does not come out vigorously
with a hissing sound, check the
following:
• Make sure that the air tube is
attached firmly to the gun
• Make sure the air supply connections
are secure
ION INJECTION TEST
When the trigger is completely pulled,
the gun will release an ionized air flow.
This is indicated by the illuminated green
LED located on the backside of the unit.
If the LED does not illuminate, check the
following:
• Battery installation
• Battery power
USING THE PORTABLE IONIZING AIR
GUN
To blow ionised air, pull the trigger all the
way in. Ensure that the green LED is
illuminated.
To blow air, pull the trigger halfway.
Ensure that the green LED is not
illuminated.

AIR REQUIREMENTS
Always supply the Portable Ionising Air
Gun with filtered, dry compressed shop
air. Using nitrogen is not recommended
with this product. If the air is not dry,
damage to the equipment may result
and the warranty will be voided. Dirty air
can introduce moisture and oil,
contaminating the units' emitter
assembly along with the materials to be
cleaned or neutralised.
Filters must therefore be used at all
times upstream of the air nozzle. A
water trap-type pre-filter should be used
in conjunction with an oil coalescing-type
filter. Also drain all moisture traps
regularly to prevent moisture in the line.
Several drains per day may be
necessary, especially in areas of high
humidity.
The Portable Ionising Air Gun may be
operated over a range of 10 - 65 PSI.
The specific pressure needed will
depend upon the application. Pressures
exceeding 65 PSI are not recommended
since these higher pressures are
detrimental to effective ion production,
and may damage the unit.
CAUTION: These air nozzles are not
explosion proof. Do not use in
environments where volatile materials
are present.
